Well I've decided to give FS2004 a second chance...I like many others experienced and still am experiencing terrible frame rates with a high performance machine (2.4 running 2.9 and GeForce 4200Ti card) ILS approach into YWG gave me an average frame rate of 7 tonite. (Done all the tweaks) I have very limited HD space left over due to FS2002 still being installed (less than 1 GB)... the question then is will FS2004 be effected by this? Does it cache anything and it can't with my limited HD space now?? Or is it something else somewhere?Chris

In a sense, yes. Almost all programs write stuff to the temp directory, so if there's not enough space, it will have to do a lot of disk swaps, so it'll affect your frame rates.I would recommend doing a defrag and scandisk of your hard drive. If you can afford to install another HD, move FS2002 or some other apps you don't need to that other HD.
